As title guys a bit of a weird one, TX4 loses temperature whilst going say going 5ph and above, it’s fine driving in town no issues, doesn’t overheat and temp is bang on heating works as it should, but as soon I hit the dual carriageway or motorway temptreyure goes down down, and then there’s no heat only cold air, back in town and it’s back to normal temp and heatings back, any ideas what I should look at or change.
As always any advice appreciated
The Tx1 used to do that but it had a summer or winter Thermostat put the winter one in and it was ok
